Now this is really odd: a) I don't have access to the timing or the caching. b) When I booted from the floppy last night and did wd(1,a)/kernel IT BOOTED JUST FINE! ???? So the next step is to try to load booteasy onto the first drive. man -k boot doesn't tell me anything, nor do any other combinations of other related words; how do I change it from the command line w/o having to reinstall BSD (sorry for the obviously ignorant question; I'm not new to Unix, but I am pretty new to complete and total system manipulation like this). I can't figure out why FreeBSD didn't load in the first place from booteasy. Is there something maybe in booteasy that causes it to behave funny on my particular machine? Thanks all! I think you folks that are working on the development of FreeBSD are doing a bang-up job and get criticized far too much by those who don't appreciate the magnitude of what you're trying to do/have done/are doing. We're using FreeBSD here to do some very simple database work (nothing fancy) for dial-up use for data collection, and it is SO MUCH EASIER to do this type of work from FreeBSD than it would be under any kind of windoze system.
